Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum coating equipment, specifically relating to a vacuum coating equipment for rapid cleaning. Background Technology

[0002] Vacuum coating equipment is a device that coats workpieces under high vacuum. Before coating, the workpiece (punch, chip, mobile phone glass, etc.) needs to be cleaned to remove grease, dust and other contaminants from the workpiece surface to prevent contaminants from affecting the coating quality.

[0003] When coating punches in a vacuum coating equipment, the punches need to be cleaned. The worker first places multiple punches circumferentially at equal intervals on a cleaning tray, then stacks the cleaning trays on a cleaning rack, and finally places the cleaning rack containing the punches into an ultrasonic cleaner for cleaning. After the punches are cleaned, they can be coated.

[0004] Existing vacuum coating equipment has the following problems and defects when cleaning punches: workers need to manually place the punches on the cleaning rack. Since the speed of manual placement by workers is limited, loading and unloading punches on the cleaning rack will take a lot of time for small and large batches of punches, which seriously reduces the overall production efficiency of coating. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum coating device with a simple structure and reasonable design for rapid cleaning in order to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A vacuum coating device for rapid cleaning includes a fixed base, which consists of an upper disc, three connecting columns and a lower disc from top to bottom. The upper disc of the fixed base is rotatably connected to a drive shaft with its axis extending from top to bottom, and a feeding mechanism is provided on the drive shaft.

[0008] The feeding mechanism includes a drive unit mounted on the drive shaft. A reciprocating screw is fixedly mounted at the bottom of the drive shaft and is rotatably mounted on the bottom of the lower disk of the fixed base. Locking units are circumferentially equidistantly mounted on the three connecting columns of the fixed base. Each locking unit includes a fixing frame fixedly mounted on the three connecting columns of the fixed base. The fixing frame is locked to the three base plates by the locking units. The feeding unit is mounted on the lower disk of the fixed base.

[0009] As a further optimization of this utility model, the feeding unit includes three sliding rods circumferentially and equidistantly arranged on the top of the fixed base chassis. Each chassis is slidably disposed on the sliding rod. Each chassis has a feeding shaft rotatably disposed on the top and slidably sleeved outside the sliding rod. The driving unit includes a driving wheel fixedly sleeved on a reciprocating screw. Each feeding shaft has a driving disc fixedly sleeved on it. Each feeding shaft has a feeding disc located above the driving disc fixedly sleeved on it. Each feeding disc has a feeding hole.

[0010] As a further optimization of this utility model, each of the feeding shafts is fixedly fitted with a fixing disc located between the drive disc and the feeding disc.

[0011] As a further optimization of this utility model, each of the drive disks is provided with multiple placement holes equidistantly on its circumference, and the feeding holes are larger at the top and smaller at the bottom and correspond one-to-one with the placement holes.

[0012] As a further optimization of this utility model, a movable block that is threadedly fitted onto the reciprocating lead screw is slidably sleeved on it. A receiving plate is fixedly provided at the bottom of the movable block. Three sliding plates are fixedly provided at equal intervals around the circumference of the receiving plate, and the three sliding plates are all slidably mounted on the inner wall of the corresponding fixed seat connecting column.

[0013] As a further optimization of this utility model, the locking unit also includes three circumferentially equidistant and fixedly mounted top plates on the top of the receiving plate. The top of the front top plate is inclined downward from front to back. Each chassis has a fixing groove. The fixing frame has three circumferentially equidistant sliding grooves and three circumferentially equidistant unlocking holes. A locking plate is slidably mounted inside each sliding groove. The front end face of the front top plate is inclined downward from front to back. Each locking plate and the inner wall of the corresponding sliding groove are provided with a locking spring.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. An external motor drives the drive shaft and drive unit to work, which in turn drives the drive wheel to rotate. The drive wheel then drives the drive disc and the unloading disc to rotate synchronously. This allows the punches on the conveyor belt to fall into the drive disc one by one through the unloading disc, thus completing the cleaning and preparation work for the punches before coating in a stable and efficient manner. At the same time, for cleaning a large number of small-sized punches, it can effectively save the cleaning and preparation work of the coating equipment and reduce the overall coating time.

[0016] 2. The external motor drives the reciprocating screw, which, in conjunction with the moving block and locking unit, enables the rapid installation and removal of the chassis holding the punch. This further reduces the cleaning preparation work before punch coating, thereby reducing the waiting time of the cleaning equipment, improving equipment utilization, and thus increasing overall production capacity.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, a vacuum coating equipment for rapid cleaning includes a fixed base 1. The fixed base 1 consists of an upper disc, three connecting columns and a lower disc from top to bottom. A feeding mechanism 4 is provided on the fixed base 1. The feeding mechanism 4 includes a drive shaft 2 with its axis extending from top to bottom, and the drive shaft 2 passes through the top of the upper disc of the fixed base 1.

[0023] The feeding mechanism 4 includes a drive unit 41 mounted on the drive shaft 2. A reciprocating screw 5 is fixedly mounted on the bottom of the drive shaft 2 and is rotatably mounted on the bottom of the lower disc of the fixed base 1. Locking units 43 are circumferentially equidistantly mounted on the connecting columns of the three fixed bases 1. The locking unit 43 includes a fixing frame 435 fixedly mounted on the connecting columns of the three fixed bases 1. The fixing frame 435 is locked with three chassis 6 by the locking unit 43. The feeding unit 42 is mounted on the lower disc of the fixed base 1.

[0024] During operation, the worker uses the locking unit 43 to attach the chassis 6 to the fixed frame 435, and then starts the external motor. The external motor drives the drive shaft 2 and the drive wheel 411 to rotate. Then the drive wheel 411 drives the unloading unit 42 to work, so that the punches are placed one by one on the chassis 6. This not only reduces the contaminants on the punches caused by manual placement, but also replaces manual placement of a large number of punches quickly and efficiently, effectively reducing the preparation time before cleaning the coating equipment and improving the overall coating efficiency.

[0025] While the unloading unit 42 places all the punches on the chassis 6, the reciprocating screw 5 simultaneously drives the unloading unit 42 to work. In conjunction with the locking unit 43, the fixing frame 435 releases the restriction on the chassis 6, allowing the unloading unit 42 to move the chassis 6 with the punches placed on it downwards. When the chassis 6 moves to the bottom, the worker places the chassis 6 with the punches on the cleaning rack, and then sends it into the ultrasonic cleaning machine for cleaning. The unloading unit 42 quickly disassembles the chassis 6 with the punches placed on it, which not only further reduces the preparation work before cleaning in the coating process and reduces the time required for the overall coating, but also reduces the idle time of the equipment and improves the overall utilization rate of the equipment.

[0026] like Figure 1 , Figure 2 As shown, the feeding unit 42 includes three circumferentially equidistant sliding rods 421 arranged on the top of the base 1. Each base 6 is slidably disposed on the sliding rods 421. Each base 6 has a feeding shaft 422 rotatably disposed on the top of the sliding rods 421. The drive unit 41 includes a drive wheel 411 fixedly disposed on the reciprocating screw 5. Each feeding shaft 422 is fixedly disposed on a drive disc 412. Each feeding shaft 422 is fixedly disposed on a feeding disc 424 located above the drive disc 412. Each feeding disc 424 has a feeding hole.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, each feeding shaft 422 is fixedly fitted with a fixed disk 423 located between the drive disk 412 and the feeding disk 424.

[0028] like Figure 2 , Figure 3As shown, each drive disk 412 has multiple placement holes equidistantly spaced around its circumference. The material feeding holes are larger at the top and smaller at the bottom, and each hole corresponds to a placement hole.

[0029] During operation, the worker uses locking unit 43 to place the three chassis 6 sequentially from top to bottom onto sliding rod 421, and then locks them onto fixing frame 435. Simultaneously, all three drive discs 412 engage with drive wheels 411. After all chassis 6 are secured, the worker starts the external motor and the conveyor belt for conveying punches. It should be noted that the worker needs to adjust the conveyor belt's transmission speed according to the rotation speed of unloading disc 424, ensuring that the conveyor belt sequentially transports one punch at a time to the top of unloading disc 424. The motor drives the feeding shaft 422 and the reciprocating screw 5 to rotate. The reciprocating screw 5 drives the drive wheel 411 to rotate synchronously, which in turn drives the three drive discs 412 to rotate. The drive discs 412 drive the feeding shaft 422, the fixed disc 423, and the feeding disc 424 to rotate synchronously, so that the punch on the conveyor belt moves through the feeding hole to the placement hole. The feeding hole, which is larger at the top and smaller at the bottom, makes it easy for the punch to enter the placement hole of the drive disc 412. The fixed disc 423 can fix the punch placed on the drive disc 412.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, a moving block 44 with threaded engagement is slidably sleeved on the reciprocating screw 5. A receiving plate 45 is fixedly installed at the bottom of the moving block 44. Three sliding plates 46 are fixedly installed at equal intervals around the circumference of the receiving plate 45, and the three sliding plates 46 are all slidably installed on the inner wall of the connecting column of the corresponding fixed seat 1.

[0031] like Figure 2 , Figure 3 As shown, the locking unit 43 also includes three circumferentially equidistant top plates 431 fixedly mounted on the top of the receiving plate 45. The top of the front top plate 431 is inclined downward from front to back. Each chassis 6 is provided with a fixing groove. The fixing frame 435 is provided with three circumferentially equidistant sliding grooves 433. The fixing frame 435 is provided with three circumferentially equidistant unlocking holes. Each sliding groove 433 is slidably provided with a locking plate 432. The front end face of the front top plate 431 is inclined downward from front to back. Each locking plate 432 and the inner wall of the corresponding sliding groove 433 are provided with a locking spring 434.

[0032] During operation, the operator first places the three base plates 6 sequentially onto the sliding rod 421 from top to bottom. Then, the fixing grooves of the three base plates 6 are aligned with the sliding grooves 433 on the fixing frame 435, so that the locking plate 432 fixes the base plate 6 onto the fixing frame 435. The external motor drives the drive shaft 2 and the reciprocating screw 5 to rotate, causing the moving block 44 to move up and down. The moving block 44 drives the receiving plate 45 to move synchronously. The receiving plate 45's stability is controlled by the sliding of three sliding plates 46 along the inner wall of the connecting column. As the moving block 44 drives the receiving plate 45 upwards, the receiving plate 45 drives the three top plates 431 to move synchronously, causing the three top plates 431 to... Each plate 431 is inserted into the fixing frame 435 through the corresponding unlocking hole. The top of each plate 431 contacts the front face of the corresponding locking plate 432, causing each locking plate 432 to disengage from the corresponding fixing groove and gradually compress the corresponding locking spring 434. This causes the chassis 6 to detach from the fixing frame 435 and fall onto the receiving plate 45. By quickly disassembling and installing the chassis 6, the flow rate of the punch coating is increased, the connection speed of the entire production system is accelerated, and the speed of the entire production system is improved. Subsequently, the moving block 44 drives the receiving plate 45 and the three chassis 6 with punches placed on them to the bottom, making it convenient for the staff to remove the chassis 6 and install it on the cleaning rack for the next cleaning work.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
